AUTOMOBILE SAFETY-LOCK AND EMERGENCY-BRAKE.

' Specification of Letters Patent.

Application filed December 4, 1916. Serial No. 134,966.

To all whom it may concern:

Be it known that 1, CHARLES F. SCHMIDT, acitizen of the United States, and resident of St.-Louis, Missouri, have invented certain new and useful Improvements in Automobile Safety-Locks and Emergency-Brakes, of

which the following is a. specification.

.Th1s invention relates toimprovements in automobile safety locks andemergency brakes, and has for its object a lever mechanism located beneath the body and in proper relation with the chassis, and by the manipulation of a lever in close proximity with the seat for manipulating the machine advancing arms into the drive wheels between the spokes. v

A further object of my invention is to provide a mechanism in close proximity with ating lever relativeto the seat.

,ring to the drawing in detail 3 indicates 'the rear axle and manipulated from the front' end ofthe machine for projecting arms between the spokes so as to lock the machine-and prevent the machine from bestolen. when left at a siding and also the device may be manipulated to stop the ma:

and-rear running gear sho ingthe application of my improvement.- I

Fig. 2, is a central sectionalview showing the location of the mechanism and its oper- In carrying'out my invention and refeirtie chassis on the ordinary automobile. The frame is composed preferably of angle or channel bars 4:; to this frame is attached and properly located the rear axle 5 to whlch are mounted the traction wheels 6, this being of the ordinary structure. I

At a point convenient with the rear portion ofthe truck I support my improvement which consists of a pair of rods7 and 8, projecting through and operating 1nv openings formed in v bars 4; their free ends 9 being normally 111 a position close to thel spokes yet preventmg contact therewith while the wheels are in mot-ion. The bars are supportedin hangers 10 conveniently located and to the opposite ends 11 of these rods is attached a fulcrum 12, which consists of a pair of arms plvoted together at the point indicated by the numenal 13 and to this pjivot )1I1tis attached an operating rod ltwhich'is su orted in the frame or channel or angle.v

'era ting' lever,

suitable hangers 15, and said rod extending forwardly to the front part of the machine and plvotally attached to a connecting rod Mana a... 4,1918.

16 which in turn is connected to a hand opcrating lever 17. a

The lever-lT-s pivoted to the frame or body' of the car at the point indicated by the The lever 17 which is placed in a vertical or locked position as shown in Fig. 2 will bring the fulcrum 12 in approximately a horizontal position advancing the rods 7 and 8 so that the ends 9 will project between the spokes thus locking the wheels and preventing them from turning, thus forming a safeguard which prevents the machine from bein stolen while on a siding. j

r en the lever is unlocked it is thrown forward so that the fulcrum will assume the position as shown in Fig. 1, and in order to prevent vibration during the movement, of the machine I ,place at a convenient location on one of the'rods 7 a spring 22 which will hold the device in an unlocked position.

In addition to the locking feature to prevent the theft of therjmachine it may be used as an emergency brake whenever such case presents itself.

The device. is simple in construction and can be arranged to be attached to any standard automobile with little expense and without in any way interfering with the general mechanism of the car 7 Having fully described my invention what I claim is:

An automobile safety lock and emergency brake comprising a hand operating lever pivotally mounted to the floor of an automobile body, an operating rod slidably mounted in bearings secured to the underside of the automobile body, a. connecting rod connecting one end of the operating rod to the lower projecting end of the hand op a pair of toggle arms connected to the rear end of the operating rod,

a pair of locking rods connected to the ends of the tbggle arms and being supported in bearings attached to the automobile frame,

a spring located on one of the looking rods for. returning the locking rods totheir aormal position when. the same is releaased, the

locking rods being placed. in a, posnzion so as 5 to permit the free ends to be advanced between the spokes of the wheel and. new? the arm, substantially spooified.

In testimohy whereof, I have signecl'my name to this sgqecification, in presence of two subscribing witnesses.
